VALTER C. MARMON, OF INDIANAPOLIS, INDIANA,ASSIGNOR TO THE NORDYKE & MARMON COMPANY, OF SAME PLACE.

SEPARATING AND BOLTENG MACHINE.

SPECIFICATION forming part of Letters Patent No. 655,881, dated August 14, 1900. Application filed November 3, 1899. Serial No. 735,686. (No model.)

T0 all whom it may curl/corn:

Beitknown that I, WALTER G. MARMON, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Separating and Bolting Machines,of which the followingis a specification.

My invention relates to that class of sifting and separating machines by which mill prodnets are suitably graded, and especially is an improvement upon or addition to that machine which forms the subject-matter of the application of Allen 0. Brantingham, filed July 3, 1899, SerialnNo. 722,689; and it consists in a means whereby the direction of the material in passing through the machine may be variably controlled, so that upon certain occasions the product may be caused to be discharged in one direction and into a certain selected receptacle or receptacles and at other times may be caused to be discharged in another direction and into another selected receptacle or receptacles.

Said invention will be first fully described and the novel features thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 is an elevation of one side of a section of a machine of the character described as seen from the dotted line 1 1 alongside Fig. 2. Fig. 2 is a vertical sectional view as seen from the dotted line 2 2 in Fig. 1; Fig. 3, a view as seen from the dotted line 3 3 in Fig. 2; Fig. 4:, a horizontal sectional view as seen when looking downwardly from the dotted line 4 4 in Fig. 3; Fig. 5, a horizontal sectional view, on an enlarged scale, as seen from the dotted line 5 5 in Figs. 1 and 6; Fig. 6, a transverse detail sectional view as seen from the dotted line 6 6 in Fig. 5; Fig. 7, a detail front elevation illustratingthe construction and arrangement of one of the operating-levers and its connection to the bridge-bar and showing also, by means of dotted and full lines, the two positions of the handle end of said lever; Fig. 8, a detail transverse sectional View through the handle end of the lever and the detent which it travels over and with which it engages as seen from the dotted line 8 8 in Fig. 7; Fig. 9, a

transverse sectional view-at the central or pivot or fulcrum point of the lever as seen from the dotted line 9 9; Fig. 10, an under side plan view at the point where the lever engages with the bridge-bar, showing the arrangement of the engaging member; Fig. 11, a detail transverse sectional view as seen from the dotted line 11 11 in Fig. '7, showing the said engaging member and the parts to which it is connected; Fig. 12, a perspective view illustrating the shifting-gates and the rods by which they are connected and operated and showing in detail the means Whereby the rods are connected to the gates; Fig. 13, a detail vertical sectional view as seen from the dotted line 13 13 in Fig. 12; Fig. 14, a horizontal sectional view as seen from the dotted line 14: 14 in Fig. 12; Fig. 15, a vertical sectional view as seen from the dotted line 15 15 in Fig. 12, and Fig. 16 a detail elevation of one of the dovetailed heads which are used in making the engagement between the rods and the gates.

The frame, the sieves, the receptacles, and the general means for operating the machine are by preference the same as those illustrated in. the Brantingham application, Serial No. 722,6S9,above referred to, and are thought to need no special description. I, however, mount upon any desired number of the sieves in said machine shifting-gates by which the open sides of said screens or sieves, through which the treated material is discharged therefrom, may be opened and closed and the discharge of material shifted at will from one side of the machine to the other, so that the material or product may be shiftably directed out of the machine or so that the product of one or more sieves may be directed out of the machine at one side and the product of the remaining sieves of the set at the other side at will. In Fig. 2 of the drawings I have reproduced substantially what is shown in Fig. 3

of the drawings of the Brantingham applica' tion above referred to, except that upon the lower six sieves I have shown my improved shifting-gates applied so that said six sieves may be caused either to discharge in the ISO same direction as the others of the set, as those of the Brantingham do, or at will caused to discharge on the opposite sides, so that the entire product may either (as in Brantinghams machine) flow into one receptacle or be divided and a part flow into one receptacle and a part into another receptacle, as may be desired. I may here remark that the number of receptacles in the bottom of the machine is, as shown in Fig. 4: of the drawings, increased by one over the number used in a machine of similar arrangement and capacity by Brantingham; but otherwise I have shown no change in the structure of the machine proper from the Brantingham construction. The arrangement in general is shown in Figs. 1 to 4, inclusive; but the details,which will now be described ,are shown more clearly and on a larger scale in the remaining figures of the drawings.

Referring now especially to Fig. 5, it will be seen that the two gates 1 and 2 are mounted upon the rods 3 and at, which rods are connected together by a bridge-bar 5 and (through said bridge-bar) are actuated by means of a lever 6. In said Fig. 5 one position of the parts is shown by means of dotted lines and the other position by means of full lines, and it will be observed that in each case one of the otherwise open sides of the sieve upon which the device is mounted is closed by the corresponding gate, while the other of said sides is open, its gate being positioned at a little distance away.

It being desirable that the parts should be assembled and disassembled easily, I have made them of a peculiar construction. On the ends of the rods 3 and 4 opposite from those ends to which the operating-lever is connected I have placed small dovetailshaped heads 7, and upon the face of the gate 1 I have placed corresponding members 8, having dovetailed grooves adapted to receive said dovetail heads. The gates 1 themselves, as best shown in Figs. 12 and 15, have outturned lips l, which extend out over the heads 7 and stop said gates at the proper place vertically when they are placed upon the ends of the rods, as will be readily understood. By this means the gates 1 are rendered easily removable and replaceable.

The gates 2 are provided with combination devices 9, having both dovetailed grooves and perforated internally screw s threaded hubs. Into these hubs the opposite ends of the rods 3 4 enter, so that the gates 2 are commonly securely attached to said rods. Short rods 10 and 11, which when the parts are assembled are, in efiect, prolongations of the rods 3 and 4, have upon their ends dovetailed heads 12,which enter the dovetailed grooves in the parts 9, while their other ends extend out and are connected to the bridge-bar 5 by means of the clamping-nuts 13 14 or in any other suitable manner. Upon the operating ends of the lever 6 is a saddle-piece 15, the arms of which extend down and embrace the bridge-bar 5 and operate the same. Centrally upon a bracket 16 is a pivot 17, which serves as a fulcrum for said lever. At or near ahandle end of said lever 6 is a latch device 18, which engages at the limit of its movement with suitable engaging points on a bracket 19, so that the gates are held in one direction or another securely.

The faces of the frames of the sieves adjacent to the gates are provided with yielding strips 3 of wool, felt, or some such material as is usually used in milling appliances to make tight joints, so that no interstices between the said sieves and said gates will be left, when the latter are closed, through which any material might pass in the wrong direction. This is illustrated more plainly in Fig. 6 than in any other figure.

The rods 3 and 4 themselves rest in 'bearings 20, which are secured upon the floor of the sieves themselves. A

Having thus fully described my said invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. The combination, in a sifting or separating machine, with a sieve having openings upon two sides, of connegted shifting-gates, whereby one of the sides may be opened and the other closed, and the open and closed sides reversed at will, substantially as set forth.

2. The combination, in a sifting or separating machine, with a sieve having openings upon opposite sides, of rods mounted in bearings in said sieve and extending through the same from side to side, gates upon the opposite ends of said rods, a bridge-bar connecting said rods, and means whereby the structure comprising the foregoing elements may be shifted from one position to the other,whereby the openings may be alternately opened and closed, substantially as set forth.

3. The combination, in a sifting or separating machine, with a sieve having open discharging sides oppositely disposed, of gates for alternately opening and closing said open discharging sides, said gates extending through said sieves and resting in bearings therein, a connecting-piece by which the two are united, and a lever engaging with and adapted to operate said connectiug-piece,substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 30th day of October, A. D. 1899.
